Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639162, here are decompositions:

13 + 8639149 = 8639162
19 + 8639143 = 8639162
31 + 8639131 = 8639162
43 + 8639119 = 8639162
73 + 8639089 = 8639162
151 + 8639011 = 8639162
163 + 8638999 = 8639162
211 + 8638951 = 8639162

Showing the first eight; more decompositions exist.
